Your first program is a simple mathematical calculation program. As we know, the straight-line distance between two points in the Cartesian coordinate plane, namely (x_1, y_1) and (x_2, y_2), is given by: d = squareroot (x_1 - x_2)^2 + (y_1 - y_2) is given by d = squareroot (x_1-x_2)^2 + (y1_y_2)^2 Write a C program that gets 4 integer values from the user, namely, x_1, x_2, y_1, and y_2, and then calculates and returns the distance according to the above formula. Your program should prompt the user for these values, accept input from the keyboard, and then print out the result. Include a screenshot that shows the results for the following values: (2, 3), (4, 5) (4, 3), (6, 5) (1, 3) (4, 2) Note that these inputs are (x, y) pairs. You may use the function double squareroot (double), found in to calculate the Square root
